Possible loop order

[DataVampire]

Hi peeps generally when I have water cooled it has just been the cpu, and with that just one rad(360).

This Time I am cooling the cpu and motherboard. and utilizing x2 rads
1x480 and a x1 360.

I will be putting all this in a corsair 900d.

480 rad in the top, 360 rad at the bottom le facing out of the window side. and will be using a ek res/pump combo(with a 240 res tube)

So I have never done this type of loop before.

Here is my idea

Res/pump combo out>360 Rad in>360 Rad out>Cpu in>Cpu out>Cross chill in>Cross chill out>480 Rad in>480 Rad out>Res/pump combo Out.

I was going to see if I could rout the final tube from the 480 out to the ress /pump combo via the back.

Any idea sugestions please

EDIT: crude image to see my case layout

just added a crude pic of my case layout(when I do it).

And yes I realise it will be way overkill. and yes I will be adding my gpu once funds allow.

I just want as clean as possible look.
